SCALE: 1 " =3' AREAS PER LINEAR FOOT OF ROAD 3" ASHPALT = 6.00 SQ. FT. 4" CLASS 6 = 9.30 S0. FT. 12" CLASS 2 = 28.60 SQ. FT. 3" ASPHALT DITCH WIDTH All Agnenate shall be of uniform quality, hard, durable,croshed stone or gravel, free from day balls, vegetable matter, or other deleterious substances, meeting the requrements in the following sections. Pavinn Aggregate shall meet CDOT grading S, SE, or SX requirements for Superpave Hot Mix Asphalt (HMA) mix designs. Aggregates meeting the requirements in the properties table shall be used to devlop the Job Mix Formula for the HMA misture. The aggegate should be composed of angular, coarse textured, cube shaped particles. Natural fine material ( A' minus) shall be screened out and discarded before crushing. Sand may be used to obtain gradation of the blended aggegate mixture but should not exceed more than fifteen percent (15 %). If the per of aggregate passing the #4 sieve is greater than ten percent (10 %) by weight of the indidual aggregate sample, plasticity will be determined in accordance with ASSHTO T 90. The gradation of the aggregates used in the mixture shall meet the criteria shown in the Aggegate Master Range Table, and shall be will graded from course to fine. The nominal size aggegate used in the HMA mixture shall not be more than one -third of the thickness of the HMA lift being constmcted. Base Course Gravel (Class 6L shall be t' minus crushed gravel or rock conforming to CDOT Class 6 gradation requirements, with an R value of seventy-eight (78) or greater. At least fifty percent (50 %) of the #4 plus fraction of the aggregate shall have at least two (2) fractured faces. Aggregate must meet a minimum hardness requirement defined by the L.A. Abrasion Test: Material loss during the test shall not exceed forty-five percent (45 %) at five hundred (500) revolutions ( AASTTO T 96). COOT Class 6 base course gravel shall be compacted to ninety-five percent (95 %) "Modred proctor" density, AASTTO T 180, between minus two percent ( -2 %) and plus three. percent ( +3 %). of optimum moisture. Subbase Gravel (Class 2) shall be crused gravel or rock conforming to COOT Class 1 or Class 2 gradation requirements, with an R value of sixty- nine(69) or greater. At least fifty percent (501 of the #4 plus fraction of the aggregate shall have at least one (1) fractured face. Aggregate must meet a minimum hardness requnement defined by the L.A. Abrasion Test: Material loss during the test shall not exceed forty -five (45 %) at five- hundred (500) revolutions ( AASHTO T 96). Subbase gravel shall be compacted to ninety-three percent (93) "modified proctor' density. AASHTHO 180, between minus two percent ( -2 %) and plus three perecent ( +3 %) of optimum moisture. Class 3 (Pit Run, river Run, Bank Run) Gravel may be substituted for crushed Class 2 gravel when recommended by the Geotechnical Engineer based upon laboratory testing on the proposed source. Thicker structural sections will be required when pit run is substituted for crushed Class 2 base course gravel. Pd run sources are subject to the approval of the Engineer. COOT Class 3 pd run gravel whall be compacted to ninty-three percent (93 %) "modified proctor' density, AASTHO T 180, between minus two percent ( -2 %) and plus three percent ( +3 %) of optimum moisture., FA Y I' DRIVING LANE r I ' DRIVING LANE 2% SLOPE 2% SLOPE SHOULDER WESTERN FUELS - COLORADO A LIMITED LIABILITY COMPANY NE#r HORIZON MINE P.0 Box 628, NUCIA, CO. 81424 I C.
